Generally its best to have the surrounds at about the 6' height as they are designed for ambient sounds that "fill" the space. keep the rear speakers about 4' apart and out of the corners.
I'm probably leaning more to the directional (for gaming). Since I already have dipoles on the sides I thought it may be overkill anyway...Dipoles are supposed to give a more dispersed localization, since their null points toward the listening position so the sound you hear is reflected off other surfaces. Monopole speakers give more localization, since you hear the sound directly from them. Which is better depends really on your personal preferences -- ambient sounds or directional helicopter flyovers
I've read the same. I'm starting to think I should wait until 11.2 receivers start coming out. The sound processing is already in place for height and wide, so I guess it's just a matter/cost of adding 2 more amps.If the processor includes support for width speakers, supposedly monopoles have an advantage in that situation. I've read claims that width causes more of an improvement to the soundstage than rear or height.
